TYPEWRITING' MACHINE.

Application filed February 25, 1928, Serial No. 257,070, and in GermanyAugust -25, 1927.

Improvement in typewriting machines.

My invention relates to typewriters and more particularly to that classof typewritcrs by means of which shorthand or stem)- graphic script maybe written.

One object of my invention is toprovide a typewriter in which the keysmay be arranged in the customary manner so that everybody accustomed tothe standard arrangemcnt of the keyboard may easily learn the use of myimproved shorthand type writer.

Another object of my invention consists in the provision of a typewriterby means of which. shorthand script as well as scrlpt in ordinaryletters may be typed, as desired.

From another aspect an object of my n 1 vention is a typewriter forstenographic script in which the distance between the typed lines mustnot by necessity exceed the distance which is ordinarily in use intypewriting script in ordinarily long hand letters.

My inve'ntion, satisfies an urgent demand for a typcwriting'machine bymeans of which a speed intyping may be attained which is far superior tothe speed of ordinary typewriting and equals at least that ofstenographing by hand. The typewritten shorthand script looks verysimilar to the handwritten script and may easily be read by everybodyfamiliar with the particular system used. fore, does away with theinconveniences and disadvantages caused by the well known fact thatordinarily hand written stenographic script can be read and transformedinto long hand script only by the same person who took the dictation inshorthand.

By means of my invention it is possible, therefore, to have a letterwritten in shorthand by one person and transformed into ordinarytypewritten script by another person.

My invention particularly contemplates the use of a system ofstenography in which a consonant, either a single or a compositeconsonant, and the vowel associated therewith are represented by asingle simple shorthand sign, and in which for representing differentsyllables comprising the same consonant associated with differentvowels, signs are used which are partly alike, signifying the associatedvowel by certain char- The invention, there-.

acteristics in their configuration and not, as

in other stenographic systems, by their position in relation to theline.

I prefer the use of such shorthand system to the. use of the mentionedother systems in which the same sign is employed for representing aconsonant associated with ditl'erent vowels and is difi'ercntlypositioned in relation to the line to express various vowels, bccause achange in the position of the sign in the accompanying drawings asembodied in a typewriter such as shown and described in the GermanPatent No. 211,568.

Fig. 1 is an elevation, Figs. 2 to 4 are sections along the respectivesection lines indicated in Fig. 1, Fig. 5 shows an example of the types,Fig. 6 a detail on a small scale.

10 indicates the customary paper carrier or paper cylinder which isjournaled in the bearings 11 forming part of a frame consisting of twolateral posts 12 connected with,- each other by an integral palte 13 Theposts 12 are shiftably mounted in guideways 13 which are attached to aframe 14. The frame 14 is movable or transportable in axial directionwith respect to the cylinder l0 and is acted upon by a. mechanism whichmoves it. step by step to the left when the keys of the typewriter aresuccessively pressed down. As such mechanisms are well known in the artand do not form part of the present invention, a description andillustration thereof is deemed dispensable herewith. The opposed facesof the posts 12 are provided with grooves for slidably accommodating aframe 15 which may be adjusted in various definite positions relative tothe posts 12.

For this purpose, brackets 16 are attached to the-plate 13 and a shaft17 is journaled therein carrying at its ends levers 18 provided withhooks 19. The frame 15 is formed'at either side with a coveixplate 20provided with two holes 21 and 22 registering with the respective book19. The shaft 17 is provided with a handle 23 and a spring 24 isinserted between the same and the post shaft 17 is turned therebydisengaging the hooks 19 from the holes. The posts 12 may then belowered by hand until the holes 22 are in registry with the hooks 19.Upon releasing the handle 23 the hooks, owing to the action of thespring 24, will slip into the holes 22 and will hold the posts 12 andthe frame 15 in their new relative position.

' In order to facilitate the manual adjustment of the posts 12' relativeto the frame 15 and to avoid a ammingofthese parts, special provisionsare made to prevent an angular displacement of the posts 12.- Theseprovisions comprise a shaft 25 journaled in the brackets 16 and having apinion 26 fixedly attached to each end. The pinions 26 are meshing withteeth 27 cut into the opposed edges of the cover plates 20. Adisplacement of the one post 12 relative to the frame 15 causes arotation of the co-ordinated pinion 26 and thereby a correspondingdisplacement of the other post 12, whereby the posts 12 are preventedfrom jamming.

The frame 15 forms two horizontal flanges 28, 29 forming a guideway fora roll 30 carried by lever 31 which is keyed-to a shaft 32. The shaft 32is supported in stationary bearings attached to the frame of thetypewriting machine and is provided with a mechanism not shown, foradjusting the shaft 32 and its lever 31 in one of three angularpositions indicated in dotted lines. As such mechanism are well known inthe art it will not be described in detail. By this adjustment of theshaft 32 the roll 30 maybe lowered into the positions 30 or 30.

The frame 15 and the posts 12 connected with the roll arecorrespondingly shifted in the guideways 13. I

The paper cylinder 10 co-operates with a type carrier carrying twogroups of types. The one group comprising the types 34, 35 and 36 isintended for use in writing shorthand script of some graphic system asdistinguished from geometrical systems. The distance of these typesequals the amount by which the frame 15 may be raised or loweredbyaction of the afore-mentioned angular adjustment of the shaft 32. Thetypes 37, 38, 39 which serve for writing ordinary script are arranged atthe same distance from each other. In the position shown in the drawingsthe frame 15 occupies its uppermost position. In this position the type341 is co-operatively correlated to the paper cylinder 10 and may bebrought into printing position by striking the key 40 as will be easilyunderstood from Fig. 5 which is self explaining, and does not need adescription as the details shown therein are simple and well known inthe art. By

changing the angular position of the lever 31 which ordinarily iseffected by pressing upon special keys, one key being provided for theuppermost position and another key for the lowermost position of thelever 31, the frame 15 is lowered by one or two steps and either thetype 34 or the type 36, as desired, is brought into operative position.

As the distance between corresponding types of both groups, such as thedistance between the types 35 and 38, corresponds with the distancebetween the holes 21 and 22, the paper carrier occupies the sameposition relatively to the'respective opposed group of types on the typecarrier regardless of whether the hooks 19 are engaging the holes 21 asshown or the holes 22.

As the three types 34, 35 and 36, being carried by a common typecarrier, are coordinated to the same key they serve for printingshorthand signs which represent the particular consonant with which saidkey is marked and various vowels coordinated with said consonant.'Ihe-configuration of three types, therefore, is preferably such that acertain part thereof is equal in all three types. This part ischaracteristic of the particular consonant, the remainder of the threeconfigurations, however, is differentiated in shape to express variousvowels which may be associated with said consonant to form a syllable.The term consonant as used herein and in the claims is intended to coveralso composite consonants like st or ch etc. If three shorthand typesare coordinated to the key marked with a consonant, as in the exampledescribed, only three different signs are available for distinguishingthe various vowels but my experience has shown me that three signs areperfectly suflicient for practical purposes. In this case, each sign,designates a vowel of a vowel group and the reader of the script mustguess from the sense thereof which particular vowel of that group is theone which ismeant by the .sign. In the German language the three groupscomprise e, ei, i and on, or a, an, a and an, or o, as, u, and iirespectively. I

In Fig. 6 I have illustrated by way of example the configuration of thetypes 34, 35 and 36 on an enlarged scale. All three types arecoordinated to a key marked with the consonant D. That part of each typesituated above the dotted line is equal to the corresponding part of theother two types. The term equal applied to these parts does not onlyindicate the identity in shape but it characterizes also the identicposition which these parts assume in printing positionin relation to theline. Those parts of the configurations which are situated below thedotted lines differ from each other and indicate the vowel associatedwith d. The type 35 may, therefore, designate in the Ill) Germanlanguage, for instance, de, dei, di, or deu, the type da, dau, da orden, and the type 36 do, do, du or dii;

The lower group'comprising the types. 37

38and 39 corresponds with the conventional .means, such as theadjustable shaft 32 with its associated parts and the adjustable posts12, must be provided by means of which anyone of the shorthand types maybe selected for typing, similar to the optional selection in ordinarytypewriters between small letter types and capital letter types whichare also coordinated to the same key and may be selected by specialkeys.

The fact that a given consonant is always written by means of the samekey no matter with what "vowel it is associated, affords the valuableadvantage that a key board may be used which substantially correspondswith the standard arrangement. This renders it possible to provide,ordinary types in coordination with the stenographic types so that bothkinds of script may be written on the same machine without requiringspecial study and exercise, or any other adjustment than the simpleshifting of the posts 12 from their one position into their otherposition.

WhatI claim is 1. In a typewriting machine, the combination comprising akey provided with a mark representing a consonant, a type representingsaid consonant in an ordinary smallletter, .a type rep'resentmg sa1dconsonant 1n a capital letter, three shorthand letter types ofconfigurations having an equal part to represent said consonant and adiflferent part to represent a vowel group associated with saidconsonant, a mechanism operatively connecting said key with said typesto cause upon the pressing of the key the movement of one of the typesinto printing position and'selecting-means for selecting any one of saidthree types for the movement into said position.

2. In a typewriting machine the combinetion comprismg a key providedwith a mark representinga consonant, three shorthand .letter types. ofconfigurations having an equal part to represent said consonant and I adifferent part to represent a vowel group associated with saidconsonant, a mechanism operatively connecting said key with said typesto cause upon the'pressing. of the key the movement of one of the typesinto printing position and'selecting means for selecting any one of saidthree types for the movement into said position.

3. In a typewriting machine, the combination comprising-a key providedwith a mark representing a consonant, a type carrier having two groupsof types one group including an ordinary capital letter type and anordinary small letter type of said consonant, the other group includingthree shorthand letter types of configurations having an e ual part torepresent said consonantand a di erent part to represent a vowel groupassociated with said consonant, a paper carrier,

an operative connection between said 'key and said type carrier tomovethe latter towards said paper carrier and a selecting mechanism forbringing said paper carrier and any desired type of said type carrierinto printingl position to each other thereby permitting t e samekey tobe used for typewriting a shorthand sign as well as an ordinary letter.

In testimony wh'ereof I aflixed my signature.
